Most people don't have integrated setups to accommodate the kind of thing you're talking about though. You're making a good case for Natal as if Sony and Nintendo don't exist but unfortunately they do and one of them is well entrenched. They cannot successfully market this product at $150 when both the Wii and Move will be cheaper. Every previous report has this peripheral being cheaper than that anyways, I'm keeping my large grain of salt handy until I hear $150 from Microsoft.
